Question

4. How does refraction work with the
glasses?​

Answer 1

Bending Light with Refraction

Lenses are pieces of glass that bend light. ... They wear glasses or contact lenses to make their sight clearer. Those glasses have specially ground lenses that bend the rays of light just enough to focus the image for the person to see properly. All lenses bend and refract rays of light.

Each light ray entering a converging (convex) lens refracts inwards as it enters the lens and inwards again as it leaves. These refractions cause parallel light rays to spread out, travelling directly away from an imaginary focal point. A biconcave lens curves is thinner at the middle than it is at the edges.
